HINGE.

Application led May 27, 1919.

To all whom t may concern.'

Be it known that I, TIMOTHY WV. Hicitnir, a citizen of the UnitedStates, residing at Abington, in the county of Plymouth and State ofMassachusetts, have invented new and useful Improvements in Hinges, ofwhich the following is a speciiication.

This invention relates to hinges of the type shown by the Upton and GrayPatent No. 699,727, dated May 13, 1902, and it has for its obj ect toprovide improvements in a hinge of this type whereby its usefulness andgeneral desirability are increased.

The invention is embodied in the improvements which I will now proceedto describe and claim.

Of the accompanying drawings, forming a part of this specification,-

Figure 1 is aside elevation of a hinge embodying the invention.

Fig. 2 is an end View, parts being broken 0H.

Fig. 3 is a section on line 33 of Fi Fig. 4 is a section on line ele-4of Fi Fig. 5 is a section on line 5 5 of Fig. 1.

Fig. 6 is a perspective view of the tongue washer. v

Fig. 7 is ay perspective view of the pintle.

Fig. 8 is a view similar to Fig. 1, showing a spring as a part of theadjustable abutment hereinafter referred to.

The same reference characters indicate the same parts in all of thefigures.

The iiXed member of the hinge includes a plate or base 12, adapted to beattached to a door janib, and a plurality of spaced apart pintle sockets13, 14 and 15, adapted to receive a pintle 17. The upper socket 13 isinternally polygonal and preferably square, as

shown by Fig. t, and the pintle 17 has a correspondingly shaped upperportion 17l titting the socket 13, and prevented thereby from turning.The main portion of the pintle is cylindrical, and is formed to passthrough the intermediateJ fixed socket 14 and the lower iXed socket 15,and through the sockets of the swinging hinge member composed of asuitable base, preferably formed by straps 20 attachable to a door, andupper and lower pintle socket-s 21 and 22, formed to receive and turn onthe cylindrical portion of the pintle.

The upper movable socket 21 is interposed between the upper iixed socket13 and the intermediate iiXed socket 14, and the lower movable socket 22is below the inter- Speccaton of Letters Patent.

mediate socket and spaced from the lower fixed socket 15.

The pintle is provided between the movable socket 22 and the lower-fixedsocket 15 with a vertically adjustable abutment, which is preferablyformed by an upper nut 211 and a lower nut 25, both engaged with a.screw thread on the lower portion of the pintle, and a tongue washer 26interposed between said nuts, the tongue 27 of said washer enga-ging alongitudinal slot 28 in the pintle. rl`he abutment aids in supportingthe movable hinge member and the door to which said member is attached.rThe adjustability ofthe abutment enables its height to be varied tocompensate for wear of the liieeting surfaces of the sockets 14: and 21,and the meeting surfaces of the socket 22 and nut 24.

Owing to the fact that the pintle is prevented from turning asdescribed, it forms an immovable support for the nuts 21 and 25, so thatthe nuts which are locked on the pintle by their bearing on thenon-rotatable tongue washer, constitute an abutment which is free fromliability to be accidentally displaced from any position to which it maybe adjusted. The upper nut 2a is locked in any adjusted position by thelower nut 2.5 through the interposed washer, the lower nut acting as ajam or lock nut. As shown by Fig. 8, the abutment may be adapted to bearyieldingly against the lower movable socket 22 by a spring 80 interposedbetween said socket and a cup washer 31 bearing on the nut 24.

The upper socket 13 of the tlXed hinge member located above the uppersocket 21 of the swinging hinge member contines the upper end` of thepintle member in close proximity to the door, and thus prevents theupper movable socket 21 from sagging outwardly, so that the said socketand the door are lirmly held in the proper relation to the j amb.

I claim:

1. A hinge comprising a fixed member including a base adapted forattachment to a door casing, and a plurality of fixed spaced apartpintle sockets, one at the upper end, another at the lower end, and thethird between the ends of said base, the upper socket being internallypolygonal, a pintle having a polygonal upper portion fitting the upperlsocket and prevented from turning by the latter, and a cylindricalportion, passing tion, between the lower and the intermediate iXedsocket and vertically adjustable on the pintle, said adjustable abutmentbeing formed by an upper nut and a lower nut, both engaged with athreaded portion of the pintle, and a tongue washer interposed betweensaid nuts and engaged with a longitudinal groove in the pintle and aswinging member including a base, attachable to a door, and upper andlower movable pintle sockets on said base` the upper movable socketbeing interposed between the'upper i5 and intermediate fixed sockets,and the lower niovfabfle socket being interposed between theintermediate'fxecl socket and the adjustq able abutment, the, upper nutbeing looked in any adjusted position .by the lower nutg2 the upper nutand thel lower movable socket. 25

In testimony whereof I have affixed my signature. I
